8. The special cable breakage detection method according to claim 1, characterized in that: the detection method comprises the following steps:
step one, judging whether the cable is seriously damaged or not: when airflow enters the inner space below the transfer box (12) through the discharge pipe (11) and is discharged from the pressure relief pipe (13), the airflow is directly blown and acts on the blades (16), so that the vertical shaft (17) can synchronously rotate under the influence of the airflow, and when whether a cable is damaged or not is judged, the initial large-scale judgment can be carried out through the rotating state of the indicating rod (19) arranged on the vertical shaft (17);
step two, judging whether middle-level damage occurs: when the vertical shaft (17) is in a normal rotating speed, the sleeve (22) rotates along with the cross rod (20), and under the action of centrifugal force, the sleeve (22) correspondingly extends out along the axial direction of the cross rod (20), at the moment, the poking piece (24) at the bottom of the sleeve (22) is not in contact with the arc-shaped bulge (25), so that no sound is generated, when the cable is damaged until a part of the radiating pipe (5) is also damaged, the air flow speed and the air pressure in the discharging pipe 11 are obviously reduced, so that the rotating speed of the vertical shaft (17) is also reduced, the extending distance of the sleeve (22) is shorter, at the moment, the poking piece (24) is frequently in contact with the arc-shaped bulge (25) in the rotating process, so that a metal knocking sound can be generated, and the purpose of facilitating a worker to further judge whether the serious cable damage condition that the radiating pipe (5) is broken is generated is achieved;
step three, determining a damaged position: when outer rubber (1) in the cable breaks, the binding force of outer rubber (1) to cooling tube (5) in this department can reduce by a wide margin, because the air current that possesses certain pressure intensity of real-time current in cooling tube (5), elastic cooling tube (5) just can take place local inflation deformation under the broken department of outer rubber (1) this moment, form the swell and the salient demonstration is at the surface of cable, because the surface of cooling tube (5) has set up fluorescence coating (14) and anhydrous copper sulfate coating (15), consequently a large amount of steam and the contact of anhydrous copper sulfate in the air react and make anhydrous copper sulfate coating (15) turn blue, thereby make things convenient for the staff to judge the damaged position fast, and the use of fluorescence coating (14), can make things convenient for the staff to judge the damaged position fast under the condition of insufficient light.
